SILO-ROOF.

Applicatioiiled November 19, 1913. Serial No. 801,782.

which the following is a specification.

This invention relates to silos, and more especially to the roofs thereof, and it has for one of its objects the provision of a roof which consists of a Vseries of independentlypivoted interlocking sections, adapted to be opened upwardly so as to uncover the entire top of the silo.

The invention has, furthermore, for its object the combination with the roof sections, of a ventilator which is removable and which, whenvin place, will assist in keeping the several roof sections in closed position. The invention has alsov for its object the combination, with aseries of roof sections which, .when assembled and closed, willV form a cone-shaped cover,of a plurality of fillers adapted to be interposed between and locked to the several roof sections when the latter are opened, thus increasing the capacity of the silo and also affording additional room for loading the same with en-y silage.

Further objects of the invention will hereinafter appear and be particularly defined in the claims.

The invention has been clearly illustrated in the accompanying drawings in which similar characters denote similar Parts, and in which- Figure 1 is a top view of a silo having a roof embodying my invention. Fig. 2 is av vertical section on line 2 2 of Fig. 1, the several roof sections being closed, and the ventilator in place. Fig. 8 is a similar section showing the roof sections opened out, and the fillers, above referred to, in Proper positions. Fig. 4 is an enlarged horizontal section of a portion of the silo roof on line 4-4 of Fig. 8. Fig. 5 is an enlarged horizontal section, fractionally, on line 5-5 of Fig. 2. Fig. 6 is a fractional top view of the roof corresponding to Fig. 3, also on an enlarged scale.

Referring to the drawings, 10 denotes the wall of a silo which is made in circular form and of any desired material, and capped with a sill 11 on which the roof is supported. In the present instance this Specification of Letters IEatent.V

roof comprises a series of adjacent sections ATE ENCE" Patented Mar. 23, 1915.'

l2 of substantially truncated. triangular form, having its side margins bent to form channeled flanges to interlock one another, one of said sections serving as what may be termed a key section which, when in closed position, locks the entire roof against opening out. The several sections are pivoted on brackets 13 secured to the sill 11, which latter may'also be provided with an annular support member 14 against which the sections can come to rest as they are folded inward, one by one, to close the roof. Byvconsidering the ycentral line of Fig. 5

it is to be noted that the roofsection member c is the first one to be folded inward l during the roof-closing operation. It will also benoted that this section has both of its marginal edges crimped tolform similar channels a which are adaptedto receive, re-` spectively, right and left handk flanges of a' pair of adjacent fillers f (Fig. 4), thelatter being usedonly when the roofV sectionsl are in their opened-out condition. `After the first section c has been folded in, vthe next adjacentsection c is folded-imbringingits right hand 'channel b over the channel-bend a of the'section c; while the channely formed.

on the leftmarginal ledge of the section 0 corresponds to that shown at Z on the right hand side of Fig. 5. In other words: all. the sections, with the exceptionof the first closing section c and the first opening section io', have a narrow channel on theirl rightwhandl edges, vwhile their left hand edgeshave wide channels sutlicient to place ,if i

so f

over the narrow channels'of the preceding l section. This sequence of sections is main.- tained throughout, so as to lit them in place l until. all the sections of the roof have been properly placed in position. It is also. to be understood that any section may be provided with an opening through which the filling-pipe may be inserted for the silo` lthis opening being normally closed by a glass g` to admit light, if desired.

While in Fig. 5 a few roofsections have been illustrated in their closed-in condition,f

I have shown in Fig. l the same roof sec-v tions opened-out and the intervening space closed with the fillersabove mentioned.

Fig.. Gy represents a top view of tlie-silo, and also shows the roof sections opened-out, with the fillers in place, and in order to maintain the roof sections in Vtheir, proper distended condition, and particularly to ioo iio.

brace them against outward pressure, I preferably employ clamping-bars 20, havingl their ends bent, as at 20, to straddle the crimped portions of a pair of adjacent roof sections; while at the inside of the silo, a bar 2l extends across the same sections, the two bars 20, 2l being drawn tightly together by clamping bolts 22, as is clearly illustrated in Fig. 6. In order to hold the fillers in position I preferably use a series of buttons 23, 24 pivoted to the opposite edges of each section respectively and extending in opposite directions, as clearly shown in Fig. 3. These same buttons may also be used to interlock the several roof sections when the latter are in closed-in condition, as clearly shown in Fig. 2, this construction naturally forming a substantial locking of the several sections.

In order to provide proper ventilation for the roof, I preferably employ a ventilator V having a collar 25, which is adapted to seat itself over all the upper ends of the closed-in sections, the body of the ventilator extending downwardly and carrying at its lower end a holding member 26 which may be slipped onto the end of said body after the ventilator is in place, and secured thereto as clearly shown in Fig. 2, in this manner still further locking the roof sections, and at the same time the ventilator, in position.

In recapitulation the manner of opening the roof is as follows:-Entrance having been gained into the interior of the silo through the liller-pipe opening, or otherwise, the member 26 is first removed from the ventilator which can then be pushed outward to release the upper ends of the roof sections; the several buttons 23, 24 are then disengaged, whereupon the first opening section 0 is swung outward into vertical position. This will allow the second section o to be opened out in a similar manner. When these two sections are thus distended, a filler-plate 7 is inserted in place and but- Ytonedl rlhe process of opening the successive sections is then repeated until the last section c has been reached and opened and held in place as above described. When the roof is to be closed the above described process is reversed, that is to sayt-the section c Vis the first one to be folded-in, and the section o constitutes the last and final closing section.

Changes may be made in the particular construction of the several roof sections, as well as in the assemblage and the pivot support of the same, without departing from the spirit of the invention.

I claim 1. 'Ihe combination with a silo, of a roof therefor comprising a series of adjacent substantially triangulary sections each having a channel in each of its side edges and adapted to be opened and closed relatively to the interior of the silo, means for pivotally supporting each section at its base on the silo-wall, and a series of independent removable fillers each having its sides bent to enter said channels for closing-in the open spaces between said sections when in opened-out Position.

2. The combination with a silo, of a roof therefor comprising a series of adjacent substantially triangular sections adapted to be opened and closed relatively to the interior of the silo, means for pivotally supporting each section at its base on the silowall, a series of independent removable fillers for closing-in the open spaces between said sections when in opened-out position, and independent clamping devices engaging the opposite faces of said roofsections and fillers, for holding the latter in position between said roof-sections.

3. rlhe combination with a silo, of a roof therefor comprising a series of adjacent substantially triangular sections adapted to be opened and closed relatively to the interior of the silo, and having grooves at their adjacent sides, means for pivotally supporting each section at its base on the silo-wall, a series of removable fillers having flanges entering said grooves for closingin the open spaces between said sections when in opened-out position between said roof-sections.

4l. The combination with a silo, of a roof comprising a series of substantially triangular sheet metal sections adapted to be closedin and opened-out, and having their margins bent to form inwardly-open channels, and a series of sheet metal fillers adapted to close the space between said sections when in open position, and having their edges outwardly bent to enter said section channels.

5. The combination with a silo, of a roof comprising a series of sections each having one of its side edges beneath the side edge of an adjacent section and having its other side edge above the edge of the other adjacent section, and a key section having both of its edges seated over the edges of the pair of adjacent sections.

In testimony whereof I afliX my signature in presence of two witnesses.
